Nuclear power by country

Countries with nuclear power plants

Nuclear power plants operate in 32 countries and generate about a tenth of the world's electricity. Most are in Europe, North America and East Asia. The United States is the largest producer of nuclear power, while France has the largest share of electricity generated by nuclear power, at about 70%. Some countries operated nuclear reactors in the past but have no operating nuclear power plants at present. Among them, Italy closed all of its nuclear stations by 1990 and nuclear power has since been discontinued because of the 1987 referendums. Kazakhstan phased out nuclear power in 1999 but is planning to reintroduce it possibly by 2035. Germany operated nuclear plants since 1960 until the completion of its phaseout policy in 2023. Austria (Zwentendorf Nuclear Power Plant) and the Philippines (Bataan Nuclear Power Plant) never started to use their first nuclear plants that were completely built. Sweden and Belgium originally had phase out policies however they have now moved away from their original plans. The Philippines relaunched their nuclear programme on February 28, 2022 and may try to operate the 1984 mothballed Bataan Plant. As of 2020, Poland was in advanced planning phase for 1.5 GW and planned to have up to 9 GW by 2040. Hong Kong has no nuclear power plants within its boundary, but imports 80% of the electricity generated from Daya Bay Nuclear Power Station located across the border, in which the power company of the territory holds stake. In 2021, Iraq declared it was planning to build 8 nuclear reactors by 2030 to supply up to 25% electric power in a grid that was suffering from shortages.

Of the 32 countries in which nuclear power plants operate, only France, Slovakia, Ukraine and Belgium use them as the source for a majority of the country's electricity supply as of 2021. Other countries have significant amounts of nuclear power generation capacity. By far the largest nuclear electricity producers are the United States with 772,221 GWh of nuclear electricity in 2022, followed by China with 395,354 GWh. + Nuclear power by country in 2022 Country Reactors Capacity(MW) Generation(GWh) %total Capacityfactor Inuse Beingbuilt 401 57 361,155 2,486,834 79% 3 1 1,641 7,470 5.4% 52% 1 0 416 2,631 31.0% 72% 0 2 2,400 1 1 1,110 4,411 11.9% 45% 7 0 5,942 41,744 46.4% 80% 2 1 1,884 13,745 2.5% 83% 2 0 2,006 15,784 32.6% 90% 19 0 13,624 81,718 12.9% 68% 54 21 52,181 395,354 5.0% 86% 6 0 3,934 29,310 36.7% 85% 0 4 5 0 4,394 24,242 35.0% 63% 56 1 61,370 282,093 62.6% 52% 4 0 1,916 14,954 47.0% 89% 19 8 6,290 41,972 3.1% 76% 1 2 915 6,009 1.7% 75% 33 2 31,679 51,908 6.1% 19% 2 0 1,552 10,539 4.5% 78% 1 0 482 3,931 3.3% 93% 6 1 3,262 22,219 16.2% 78% 2 0 1,300 10,222 19.4% 90% 37 6 27,727 209,517 19.6% 86% 5 1 2,308 14,830 59.2% 73% 1 0 688 5,311 42.8% 88% 2 0 1,854 10,124 4.9% 62% 25 3 24,489 167,514 30.4% 78% 7 0 7,123 56,150 20.3% 90% 6 0 6,937 50,018 29.4% 82% 4 0 2,973 23,180 36.4% 89% 3 0 2,859 22,917 9.1% 92% 0 4 15 2 13,107 81,126 55.0% 71% 3 1 4,011 19,300 6.8% 55% 12 2 7,343 43,605 14.2% 68% 93 1 95,523 772,221 18.2% 92%
